How can I use Flask with asynchronous programming?

You can use Flask with asynchronous programming by integrating it with libraries like asyncio or using Flask 2.0+ which supports async routes.

Can you show me a simple example of an async route in Flask?

Sure! Here's a basic example:

from flask import Flask
import asyncio

app = Flask(__name__)

@app.route('/async')
async def async_route():
    await asyncio.sleep(1)
    return 'This is an async route!'

What are the benefits of using async in Flask?

Using async in Flask allows for better handling of I/O-bound tasks, improving performance and responsiveness, especially under high load.

Are there any limitations I should be aware of?

Yes, some libraries may not be compatible with async, and you need to ensure that your code is structured to avoid blocking operations.
